WASHER LOADING DEVICE Filed Jan. 12, 1927 43 I, I i 00 46 i 49 Patented Dec. 2, 1930 UNITED STATES FATEN? QFFEE SIDNEY J. FINN, OF BEVERLY, MASSACHUSETTS, ASSIGNOR TO UNITED SHOE MA- CHINERY CORPORATION, OF PATERSON, NEW" JEESEY, A COEFORATION OF NEW JERSEY WASHER-LOADING DEVICE Application filed January 12, 1927.

This invention relates to placing per forated articles upon pins and is herein illustrated as embodied in a device for placing washers upon the pins of a rubber heel mold.

Rubber heels commonly have embedded in them a series of small washers, the holes through which register with the nail holes in the heel. These washers are commonly dish-shaped, the open sides thereof being faced toward the bottom of the heels so that the nails, when driven, will be guided into the nail holes. The molds in which rubber heels are molded and vulcanized comprise base plates having a plurality of upstanding pins which form the holes in the finished heels. Upon these pins, the washers must be placed before the so-calied biscuits of rubher are put into the molds; and the device of the present invention is adapted to perform this washer-placing operation.

The illustrated device is of the type which is operated b relative traverse between it and the mol the present invention being directed more particuiarly to the provision of novel means for displacing a washer from the stack and for holding it in position to be threaded upon a mold pin.

According to one feature of the invention the stack is supported by a plurality of members, one of which is capable of yielding; and the lowermost washer of the stack, after it has been displaced, is held by this member until it is engaged by and threaded upon the mold pin. Inthe illustrated construction, the under side of the lowermost washer is supported at its forward portion by a rigid member and at its rear portion by a yielding member; and the feed slide, referred to above, pushes the lowermost washer out of its position in the stack into a position where it is supported by the yielding member preparatory to being threaded upon the pin. P

With a construction of the kind outlined above, each washer is moved out of its stacked position prior to being engaged by a mold pin and is held in such position that the pin engages it properly.

Theseand other featuresof the invention Serial No. 160,860.

including certain details of construction and combinations of parts will be described as embodied in an illustrative machine and pointed out in the appended claims.

Referring to the accompanying drawings,

Figure l is a perspective of a device in which the present invention is embodied.

Figures 2, 3, 4t and 5 are fragmentary views in vertical longitudinal section showing different positions occupied successively by parts of the device. In these figures, certain parts of the device have been omitted to simplify the showing.

Figure 6 is a perspective of the feed slide and its operating mechanism, and

Figure 7 is a perspective of the under side of the device showing more particularly the parts which engage the mold pins.

The device comprises an elongated flat shoe 15 l'iaving its forward end bent up at 17, and a handle 19 fastened to the upper part of the upright arm of an angle iron 21, the horizontal arm of which is fastened to the shoe 15 by screws 23. The device is adapted to be moved forward and back over the rows of mold pins of a rubber heel. mold and, during the forward strokes, to deposit a washer upon each pin over which it passes. The washers 100, herein shown as of the dished type, are stacked, open sides down, in nested relation in a magazine in the form of a tube 25, the lower end of which is fast to and extends through a block 27, which extends down through an opening in the shoe 15. This block is forked at its forward end has at the outer ends of the arms of the fork up standing lugs having alined bores through which pass loosely aiined studs 29, 31 which are held in upright lugs formed at the rear end of a bracket 33, said bracket being fastoned to the shoe 15 by screws 35. The block 27 and the tube 25 may thus be adjusted about the common axis of the studs 29, 31. The block and tube are held yieldingly in adjusted angular position by means of a tension spring 37 and a stop screw 39, the latter being threaded through the upright arm of the angie iron 21. By adjusting the stop screw the angular position of the block 27 and tube 25 may be changed. It will be noted that,

This act ator is fast to the lower end 033a sins.

The enh of the which is remote from the pin 61 is pivoted to the slide .49, and a-tensionspring67 con'ectsxthe pin witiha SereWQGQ-carried by the hi ack t 3-8 which is rigid with the shoe The actuator is in the form of an arm the outer end of which nornially extends across and in front of the passageway between downwardly extending projections'i iZi. 22'? on the block 27. In front of the actue er are two guides 71, 73, fast to the shoe 15, spaced apart and having converging fa -es, one of which is shown at 173 to guide a moldpin to the actuator 55. Thetension spring 67 tends at all times to hold the actuator 5" against the rear, face oft-he guide 71, but permits the actuator to be, swung to the rear about the axis of thesmall upright, shaft 5? when said actuator is pushed against a moldpm.

In the operation of the device, the tube 25 is first filled with stacked. washers 100. The operator then seizes the handle 19'and pushes the device across a rubberheel mold, with the shoe 15 resting upon the tops of the mold-pins. Such mold-pins are comn Q arrangedingroups'which are horseshoe-shaped in outline, but the operator may select a series of pins which are approximately in line and so guide the device that the pins of the series are'receive'd successively z-etween the converging 'fac'es of the guides F igures 2, 3, 4 and 5 represent four positions of the device in its fofwhridmovement Y with respect to a stationary mold-pin 200. In Figure 2, the mold-pin is just in front of the converging guides71, 73. As the device is moved forward into the position shown in Figure 3, the actuator 55" is swung to the rear bycontact with the inold pin, nd the slide 49jis" moved frearwardly on the block 27 through; e. mal s 5.7.

The lowermost washeris not only thus displaced from the stack 'butis tilted somewhat, as shown in Figure 3, and held "in position presently to be threa-dd'upon' the inold pin. As the device is' moved :farther forward into the position shown in Figure 4, the mold' pin engages the hole in the washer; and, as the devicecontinuesits forward movement, the washer is threaded on thepin and dragged out of the stack as shown in Figure 5. Meantime, thepirhaszipassed from be neath the tube 25, the pusherz'149 has re turned to its normal forward position, the

supporting flanges 43 have risen, the lowermost washer of the stack rests upon the surface 41 and the flanges 43 as in Figure 1, and the parts are in position to deposit said lowermost washer upon the next mold-pin which is encountered.

Although the invention has been set forth as embodied in a particular device, it should be understood that the invention is not limited in the scope of its application to the particular device which has been shown and described.

In order to promote brevity as well as to point out a specific use of the device, the placing of washers upon the pins of a mold has been described and will be deferred to generally throughout the claims, but with out intending to exclude other articles which may be placed upon members other than the pins of a heel mold.

This application has been filed concurrently with application Serial No. 160,239, filed Jan. 10, 1927, in which the generic claims to subject-matter common to the construction shown in the two applications have been presented.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is 1.
